ICE-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 727,432, dated May 5, 1903.

Application filed August 2, 1902. Serial No. 118,091. (No model.)

coils oflpipe IWI, lying'horzontally and form- .To @ZZ whom, it may concern,.-

Be it known that l, AUGUSTPETER, a citi` zen of the UnitedStates, residing at Chicago, in the county of Cook andState of Illinois, have invented certain new and useful 1mprovements in Ice-Machines, and I do hereby declare the following tobe a full, clear, and

exact description of the invention, such asV will enable others skilled in the art to which it appertains to make and use 4the same.

My invention relates to a novel construction in a refrigerating-machine, the object being to providesJ device of this character in which the use of chemicals and gases is dispensed with and pure ice produced at a minimum cost; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanyingdrawings, illustrating my invention, Figure l is a central vertical longitudinal section of refrigerating appara' tus constructed in accordance With my invention. Fig. 2 is a plan section of same on the line 2 2 of Fig. 2.

The production of ice by the methods at present in vogue requires skilled labor and the use of poisonous gases, which frequently cause grave accidents. The present methods also require extensive plants in order to render the manufacture profitable. invention overcomes these objections and provides a simple and economic method Which.

can be profitably carried out on a small scale Without the use of expensive machinery. p.

Referring now to said drawings, A vindicates a large compartment, the Walls of which are constructed'in any Well-known manner to insure non-conductivity of heat. The said compartment A is divided into a plurality of smaller compartments B, C, D, E, F, and G, which I Will now proceed to describe. The said compartment B contains a continuous coil of pipe H, which is connected at one end with the delivery end of a pump I and at its other end With a secondV coil J,'lyingl in the compartment F., the connection being effected by means of a pipe K passing from the bottom of compartment B through the top thereof and thence over the top of the compartment A to the compartment E. From the bottom of the coil .I connection is made, by means of a pipe L, with a plurality of zigzag My presentY ing shelves inthe compartments D and F, the pans N, containing Water to be frozen, being supported on said coils or shelves. The uppermost coils in both compartments D and F are connected together by means of a horizontal pipe passing through the compartment E, and the other end of the coil in compartment D is connected with the next lower coil therein and the latter with the corresponding coil in the compartment F, and so on, the end of the last coil being connected with a pipe O, connecting with the suction end of the pump. The said pump receives air from a pipe P, passing through the compartment B and projecting above the latter, said pipe being provided with a valve Q at its upper end, by means of which it may be shut off when desired. The pipe O enters said pipe P adjacent the latters connection with the pump and is provided With a valve R adjacent said connection. The said compartments B, C, E, and

YG' are filled With cracked ice and salt, thus square inch has been attained in the coils the valve Q is shut od and the valve R opened, whereupon the aircontained in the coils will be kept in constant circulation,thereby economizing the consumption of heat absorbents in an obvious manner. To enable me to read the pressure and temperature, I provide a pressure-gage S and thermometer T, the latter indicating the temperature in compartment E, which is most important. The temperature of the air is maintained very low, thereby rendering the production of ice very rapid and making the latter extremely hard, thus imparting toit greater heat-absorbing properties than are imparted to the present artificial ice.

The pump may be driven from any suitable source of power.

I claim as my invention- A refrigerating apparatus comprising a compressor, a compartment adjacent same, a pipe passing through said compartment and connected With the suction end of the compressor, a Valve in said pipe, a coil in said compartment connected with the delivery end of said compressor, said compartment being adapted to contain a heat-absorbing body, a compartment adjacent said first compartment adapted to contain ice and salt, a compartment adjacent said second compartment containing a plurality of fiat zigzag coils forming shelves therein, a compartment beyond said third compartment containing a second coil connected with the coil in said first compartment, a fifth compartment containing a plurality of flat zigzag coils forming shelves therein, said flat coils of both com- AUGUST PETER.
